Mounting gy6 muffler - part # for washer or bushing (picture)
 

I have a yerf dog spider box gx150 and the muffler totally fell off. I lost the bolt that mounts the muffler to the left side of engine. The hole on flange below is way too big for standard m8 bolt is there a special washer? If so I can't find part # (I have a manual and don't see it any diagrams)

Yeah, there's a stepped rubber bushing that is supposed to fit in the muffler hole, with 2 steel washers on the bolt (one on each side of the rubber bushing).

A parts inventory for these yerfs no longer exists. You have to be creative. A couple of fender washers will do the trick

Thanks.i guess gender washers it is. Was hoping the gy6 engine was so common the mount and rubber bushing would be super common, cheap and easy to find.

Look for rubber isolators. Shouldn't be too hard to find.
